Long Tap
Long tap can be used to access the commands of the context menu. Performing this gesture raises the itemHold event. To handle it, assign a function to the onItemHold option, or subscribe to this event using the on(eventName, eventHandler) method just like it is demonstrated for the swipe gesture earlier on.

You can also specify the time period the widget should wait before raising the itemHold event. For this purpose, change the itemHoldTimeout option.
